PCM Digital <strong>Audio</strong><br />
PCM digital audio (Pulse Code Modulation) is the stereo audio that is digitally encoded onto CDs and<br />
laser discs, as well as the audio output of some broadcast receivers. For standard PCM digital audio, no<br />
prior decoding takes place to derive the stereo signal (as in Dolby Surround 2.0). Material encoded in<br />
Dolby 2.0 can also be decoded in any of the two channel modes described below.<br />
Analog <strong>Audio</strong> (Stereo or Mono)<br />
As with two channel PCM or Dolby Digital audio, the <strong>Suite</strong> <strong>7.1</strong> is capable of processing standard two<br />
channel analog signals with all of the two channel modes described below.<br />
Two Channel Decoding Modes<br />
The <strong>Suite</strong> <strong>7.1</strong> can decode two channel signals in Dolby Surround 2.0, digital PCM or two channel<br />
analog audio in any of the modes listed below including any enhancements you choose to add.<br />
STEREO - This two channel mode will active only the left and right speakers along with the subwoofer.<br />
MONO - In this mode, only the center channel and the subwoofer are active. If a stereo signal is in<br />
play, both right and left channels mix to mono and play through the center speaker.<br />
DTS NEO 6 - DTS Neo 6 is one of the few Two Channel modes that will permit you to engage your<br />
entire speaker array (<strong>7.1</strong>) when playing a two-channel source. Here, the L, C, R, SUB, LS, RS, SBL,<br />
and SBR Output channel lamps are on and all speakers are active.<br />
DTS NEO6+THX - This mode is the same as DTS Neo 6 and includes the addition of THX<br />
enhancements.<br />
PROLOGIC - Pro Logic decoding is a matrix decoding mode for two-channel soundtracks and<br />
works best with material that was specifically encoded in Dolby Surround. Here the surround channels<br />
have a mono, not stereo sound field.<br />
PROLOGIC THX - This mode is the same as Pro Logic and includes the addition of THX<br />
enhancements. Here, the L, C, R, SUB, LS, and RS Output channel lamps are on, all speakers are<br />
active, and the THX symbol is illuminated.<br />
PLII MOVIE - Pro Logic II Movie decoding is an advanced matrix decoding mode for two-channel<br />
film soundtracks and is optimized for programs or movies that are encoded in Dolby Surround. Here<br />
the surround speakers have greater spatial separation, providing a more stereo like sound field. This<br />
mode is also appropriate for video games. This mode retains the important features of Pro Logic, but<br />
with full-bandwidth stereo surround output, the listening experience is much closer to the sound you<br />
get from Dolby Digital.<br />
